Question

Using the information below. Find the velocity with which a ball reaches the ground when it is dropped from a height of 64 m. If a ball is dropped on the ground from a height of h m, then the ball reaches the ground with the velocity 4.43 √h m/sec.

Answer 1

The ball reaches a speed of

$4.43\sqrt[]{h}\text{ }\frac{m}{s}$

when dropped from a height of h meters.

When dropped from a height of 64 meters, the terminal speed would be

$4.43\sqrt[]{64}\rightarrow35.44\text{ }\frac{m}{s}$
